The house I own is about 7 years old. The laundryroom shares a wall with the master bedroom. The drain for the washer is in the wall between the laundry and bedroom. You can't start a load of wash and go to bed because when the washer pumps out the noise of the water going down that pipe (pvc) will wake you up. I have thought about adding a piece of rubber drain hose to the drain hose from the washer, long enough to reach the bottom of the vertical drain pipe. Thinking the water hitting that far down the pipe would be much more quiet. Opinions?
